Export seems to get stuck on last frame after YouTube upload.

I have exported my project and uploaded to YouTube. I used premiere Pro and lined up the work area exactly at the end of my footage. I am wondering if this is a YouTube issue or have I done something wrong? It seems that the video stops with one second left to go or possibly one frame. This prevents the video from playing the next video on YouTube. Maybe this is a YouTube issue or I have exported incorrectly?

Although a number of folk here can probably help, I'm guessing you'll get a LOT more useful repies if you posted this on the Premiere Pro forum instead. Oh, and you might include particulars such as version of Premiere, export settings, Preset used, etc.
